Tile has offered keychain-friendly trackers for a while. With its latest models, the Slim and Sticker, you can keep track of almost everything else. The Slim is the size of two credit cards, so it slips easily into wallets, passport holders, and jacket pockets. It has a 200-foot range and a "louder" ring. The Sticker is, as the name suggests, a small circular device designed to stick to nearly anything that might be misplaced, including tools, remotes, and chargers. It has a 150-foot range and a "loud" ring. Both models are fully waterproof and are available now, alongside updated keychain-friendly Mate and Pro models.
